erm, it is really up to you. Everyone has different tastes.

1) Do you want to be original and stand out from the crowd?
2) Do you like the looks?
3) Do you like the fact that it is actually a Merc SLK under the hood so it is well known to be a good engine and chassis and gearbox?
4) Do you need more than 2 seats?
5) Do you like a good compromise on performance vs looks / style and creature comforts?
