Mark was brilliant. Carried out a pre purchase inspection for me. Called me as soon as he found issues with the vehicle. Very detailed report and clear detailed pictures. Would highly reconsider

Arrived on time and diagnosed what was wrong with car, but paying £95 to just to be told what was wrong and not fixing issue is very pricey

Reply from Mark:

Arrived on time? yet 3 star? you booked a diagnostic check? which is what was carried out? you didnt book a fix? im at a loss what you think a diagnostic inspection is? plus you knew the price when you booked it? ruined my 5 star feedback, when i did everything you paid for? i mean i got £70 for that job that includes me drivng for 1hr and a half ,to get to you and back, my fuel, my car tax, my wear and tear on my car, my insurance, customer liability insurance,and dont forget the £4,000 i spent on Diagnostic equipment and last but not least my experiance, £95 doesnt sound to bad now does it? wait until you have to pay for the repair if you think £95 is expensive.
