Where are you based? I'm sure someone could arrange a test drive for you to demonstrate the Cupra experience.
Yep they launched the original Cupra in 2000 on an X-plate. Mostly they do look sleeperish with subtle bodykit, twin exhaust pipe and multi spoke alloys. It also had a 15mm lower ride height and rear anti-roll bar over and above the standard car. They came with 178bhp and 173lb/ft of torque as standard and the performance figures were quoted at 0-60mph in 7.7 seconds and 142mph flat out, making it a pretty potent car.
In late 2002 the model was facelifted with a different (much more attractive IMO) bodykit and new 17in wheels. AFAIK the changes were just cosmetic and the car was pretty much the same underneath.
Around the same time Seat launched the Cupra R model with the engine from the Audi S3 of the time. It had a larger turbo, twin intercoolers and kicked out 210bhp and 199lb/ft. The car had a different, more aggressive bodykit and 18in alloys, uprated suspension and interior, and also a larger oval tailpipe. Performance figs were claimed to by 0-60 in 7.2 secs and 147mph flat out.
In late 2003 the engine was uprated to the Audi TT225 (and then S3) spec 222bhp engine with 206lb/ft of torque. Other changes to the car were red Cupra badges instead of black ones (woo hoo!). Performance was claimed to be boosted to 0-60 in 6.9secs and 150 top, but many claim that there is nothing in it between a 210 and a 225.
I've seen plenty of adverts on the net for Cupras being sold as Cupra R's and Cupra's claiming to be standard yet having 225bhp etc. The above should
help you tell the difference hopefully
Like many have said though, get the car that suits your budget, but either way, if you do get bored of it and/or the tractors in your area suddenly get a lot faster then an ECU remap will unleash plenty more power and performance!
