| I think regardless of colour (my tumbler is red :P), that it would seem like the 8k one would seem good. Only problem, I feel, is that its 3500 til its service... but for me, I think it'd be between the £8500 and the £8k one. The £8k one cause you'd be able to fit stripes easily (I'd haggle with dealers or go private on that one), and you'd be able to enjoy the sun with the sunroof. Also, as its with the dealers, at least you have the guarantee that it'd be fairly upto scratch if they've bought it (but I'd take a mechanic along to check that one). However, I've heard a few things about the sunroof (problems that could go expensive... Perhaps a trip to the 1st gen forum?), and so it'd be a gamble.
I'm more tempted with the £8500, as this one seems to have pretty much (nearly) everything done. With regards to the half leather seats, its not exactly a biggie, but I prefer that cause leather is quite sticky in the heat...
I apologise if I wasn't much help! (But red is a wicked cool colour ;-))  |
