i like the look of em too. by all accounts they are great cars. they use a 2.5 litre 5 cylinder turbo engine sourced from a volvo. they hit 60 in around 6.5-7 seconds, and go on to around 150. you can get em in three specs, ST1, ST2 and you guessed it, ST3. All engines and kerb weights are the same with the difference being in the interior and sound system and equipment.
real life on the road speed they are very capable and will keep up with the likes of golf gti's, rs clios, ctr's and lcr's etc etc. there's not a lot in it between it and the above mentioned. with a big strong torquey engine and the presence of a turbocharger they have huge tuning potential (if you're into that sort of thing) and would cost realtively little to get it to a point where it would leave the above mentioned for dead. (provided they're not modded too of course)
however as a car in standard form, it is a very good package indeed. Not exactly cheap though with prices ranging from 18k to just over 20 iirc
