There are several that stick in my mind....

Mike R's old saph as that was the first really quick car id been in, still one of the most powerful cars ive experienced!!

For obvious reasons my brothers (Christian) RST as ive seen it since the the day he got it! Ive seen it go from standard to how it is today with everything in between! A truly spectacular car that impresses me more than alot of more powerful cars ive been in!!

Also, Stuart Beales old 3dr (think it was about 400bhp when i was a passenger) was the first 3dr id been in! Was mental, and it was the first high speed crash id had!! Racing Mike R in his lotus on the way back from the Norfolk meet and got out of shape on a roundabout, ended up doing a 360 onto the verge before waiting for the "Norfolk Convoy" to arrive! LOL!!
