They both look like nice clean cars, but they are both poverty spec, I.e. no options.
And If i'm not mistaken, the second car claims to have 18" alloys, but they look like the 17"...
If you can, hold out for some of the more poplular extras - I really wish I had when I bought mine - it'll make the car nicer and easier to shift in a few years time.
It's all relative, but there's a general consensus that things like these are most desirable:-
18" Monza (sell? Fund the CH's),
RNS510 Sat-Nav,
Multi-Function Steering Wheel,
DSG,
Leather,
Xenons.
It's a bit of a balancing act - a lot of things can be added fairly easily after market the shouldn't put you off what could otherwise be a good car:
18" Monzas can be retro fitted
RNS-510 can be retro fitted (budget for the revised controller too)
Leather is over rated... Unless looked after well, will sag and put off future buyers. Unless you like it - ETTO
The best options to hold out for are DSG, Xenons (or Winter pack) and Highline:
With DSG, it's cheap and easy to add the MFSW if required as unlike the manual, the steering wheel is already wired for it (due to the paddles)
Xenons are very costly to retro fit
properly. If you cant find a car with them, next best option is the Winter pack, as this will give you head light washers which you need for Xenons - and are the hardest bit to install. Then all you have to add as the lights and the levelling system, still not cheap but this is the easiest route to retrofit.
Finally Highline - again not impossible to retro fit, but the additional coding and control modules can bump up the cost very quickly.
The difficulty I was having finding a GTI to my spec was one of the reasons I gave and went for an R32 instead - you get so much more as standard. The premium I've paid for the R (initial vehicle cost, not running cost!!) will definitely out weigh the cost of adding everything I wanted on a GTI.
