I'm sorry to have to say this, but you Sir, are a blithering idiot.
TurboFit have cocked up many, many peoples cars and cost many members on here lots of money. When TurboFit went pop, (which was inevitable due to the 'quality' of their workmanship), most of the TurboFit staff, and cars, went straight over the road to JDP. Do you honestly expect people on here to believe that, because it's a different company, they will change their working practices? - Come on!?!
Secondly, considering the above, you expect people on here to recommend other people go to where these people now work? - Please!?!
As for the advertising. Again, you really are showing your severe lack of intelligence. Yes, TurboFit paid to advertise on here. At one point, many people thought they were the best thing since sliced bread. Now that it's become apparent that they are the automotive equivalent to the black death, can you see any advertisements for them? People thought Milli Vanilli were good until it was discovered that they were a farce!
JDP motors may well have many satisfied customers. Great. If they stick to servicing and MOT's, I'm sure they'll be fine.
The Tuning/modifying market is a very different game.
Now, be a good little boy and go back to your Audi club where spark plugs are the pinnacle heights of performance tuning.
