Bob's Mechanical Repairs is a physical workshop in Birnam, Perthshire. We do not have premises in St Andrews. This page is an independent garage guide written by Bob — no St Andrews garage is represented here unless a named, verified partner garage is listed on this page. Bob can give written advice on your vehicle by email; the network is still looking for one verified partner garage in St Andrews.
We're still looking for a St Andrews garage — but Bob can help today
The network behind this page is a workshop in Birnam, Perthshire recruiting independent garages around the country. A garage only gets named once its application has been reviewed. That has not happened in St Andrews yet, so no local garage is represented here.
You can still get a straight answer today: ask Bob online. Warning light, odd noise, failed MOT, or a quote you are unsure about — he replies in writing, and since he cannot do the job in St Andrews there is nothing for him to sell you.
Ask Bob about your car — If you run a garage in St Andrews, you can apply to be the one listed here.
How this guide works
This page is a reference guide, not a booking page for a workshop in St Andrews. It sets out the typical scope of MOT testing, the price range drivers usually see, and the questions worth asking so you can compare quotes properly.
Availability and the final price always depend on the garage you choose. Anything quoted here is a guide figure taken from typical UK independent-garage pricing, not an offer.
MOT classes explained for St Andrews drivers
MOT testing in St Andrews covers Class 4 (cars and light vans up to 3,000kg, DVSA maximum £54.85), Class 5 (minibuses and larger passenger vehicles, 13+ seats) and Class 7 (commercial vans between 3,000kg and 3,500kg, DVSA maximum £58.60). Most drivers need a Class 4 test; van owners should check the plated weight before booking, because a Class 7 vehicle cannot legally be tested on a Class 4 bay.
The published DVSA maximum covers the standard MOT test, including the emissions check. If a garage quotes anything additional, ask for the optional or extra work to be set out in writing. A retest may be free where the vehicle is left for repair and retested within 10 working days, subject to the retest conditions published on GOV.UK. If you are not sure which class your vehicle falls into, check the V5C for the revenue weight rather than guessing from the body shape.
How to choose a garage in St Andrews
Check the garage is on the DVSA register if you need an MOT, ask whether the technicians are IMI or City & Guilds qualified, and look for recent reviews that mention the same kind of work you need doing.
Ask for a written quote before any work starts, ask whether old parts can be shown to you afterwards, and confirm that servicing will be recorded to the manufacturer schedule so a warranty stays intact. A garage that will not put a price in writing is not worth the risk.
Questions worth asking before you book
Is the quoted price inclusive of parts, labour and VAT? Will diagnostic time be credited against the repair if you go ahead? What happens if extra faults are found once the car is stripped? How long will the car be off the road?
On older vehicles it is also worth asking whether the garage will supply a photo or video of anything they say needs replacing. Some garages can provide this — it is worth asking.
Driving conditions around Fife
Local roads shape what wears out first. Where you have a lot of stop-start traffic, brakes and clutches go early; on rough rural surfaces it is suspension and tyres; near the coast it is corrosion. Mention the kind of driving you do when you get a quote — it changes what a garage should be checking.
Bob's advice for St Andrews drivers — from the Birnam workshop
Robert McMahon — Bob to customers — has been a mechanic for 32 years and runs Bob's Mechanical Repairs in Birnam, Perthshire. He cannot work on your car in St Andrews, and this page never pretends otherwise. What follows is the advice he gives across the counter every week about MOT testing: what the job involves, what it should cost, and where drivers get caught out. It applies the same whether the car is on his ramp or on someone else's.
Batteries, charging and the electrical faults that fool people in St Andrews
A car that cranks slowly on cold mornings and throws unrelated warning lights is usually telling you about the battery, not about the lights. Modern cars with stop-start need an AGM or EFB battery, and fitting a standard one is a false economy — it will be flat within a year. Budget £110–£220 for the right battery, plus a small charge where the battery has to be coded to the car.
If a battery keeps going flat while the car is parked, that is a parasitic drain and it needs a proper current-draw test, not a new battery. It is an hour or two of diagnostic work and it is worth paying for. Ask any St Andrews garage quoting for MOT testing whether they can do a drain test before they sell you a third battery.
Buying a used car? The checks that matter more than the mileage
Read the MOT history on GOV.UK before you view anything. Repeated advisories for corrosion, brake imbalance or suspension mean deferred work you are about to inherit. Mileage that jumps around between tests means the clock is worth questioning.
Then check for outstanding finance, write-off markers and stolen records — that is a £19.99 check against a car costing thousands. A cold start, a test drive from properly cold, and a look under the oil cap tell you most of the rest. Bob does this every week on cars brought into the Birnam workshop before purchase, and the same routine works wherever you are buying in St Andrews.
Warning lights: what to stop for and what can wait
Red means stop as soon as it is safe: oil pressure, coolant temperature, brake system, charging. Driving on with an oil pressure light is how engines die in a mile. Amber means get it looked at soon — engine management, ABS, tyre pressure, glow plug.
A flashing engine management light is the exception to "amber can wait": it usually means a misfire that is dumping raw fuel into the catalytic converter, and that converter is the expensive part. Pull over, get it recovered, and save yourself £600–£1,200.
The short version
None of this needs a garage visit to act on. Check it yourself, ask better questions at the counter in St Andrews, and send the quote to Bob in writing if the numbers still do not look right.

Garage owners in St Andrews
How do independent garages in St Andrews win work online?
Ranking in St Andrews comes down to answering the questions drivers actually type before they book — cost, timescale, what's included. Chains do that at scale; most independents never get the chance. This guide does it for MOT testing, and one St Andrews garage can apply to be the workshop named on it once the application has been reviewed.
How do I get my workshop onto the St Andrews guide?
Yes — one garage per town. Apply through the garage partnership form and Bob reviews it personally. If approved and activated, your workshop name, contact details and website appear on this page, and eligible enquiries may be offered under the agreed partnership terms. No long contract, cancel any time.
What do partner garages in St Andrews actually get?
Two things: the named listing on this page, and the software Bob's own garage runs on — job cards, MOT reminders, invoicing and customer records. Both start only once the application has been reviewed, approved and activated, and no volume of enquiries is promised before that.
