I have done 21k with no problems love it all apart from the vague feel of the steering and the depreciation!
Top speed plenty (2:00 am long straight).
Chip and K&N's made a noticeable difference and the slotted rotors with red stuff pads help with the dust (not to mention stopping power)!
I have looked at changing to the SRT6 until quoted a trade in price; the SRT will probably drop even more!

Interested in the driver’s seat problem you had rob265, mine has developed a real bagginess in the bottom of the seat (I am 13 stone before you suggest lol).
