2014 and up has the DCT transmission. you don't want an R8 with paddle shifters (or a Gallardo) without the S-Tronic. you can also get a 6-speed manual with the R8 V10 if you want to go old school. those seem to be the most sought after gen 1 R8's these days. the S-Tronic has 7 gears instead of the R-Tronic's 6, but more importantly, no lag when shifting.
if you want maximum R8, the GT is the one for that era. extra aero, extra power, less weight. between the GTR and R8, i'd go R8 all day. the GTR might be quicker from the stop, but it's a clunky rubbish car. the Audi is a classy, mid-engined Supercar with a lot of race heritage and credibility.
2014 R8 V10 should do just fine for you mate... :biggrin:
