I have a Astra SRi 1.4 Turbo 150bhp and it a beast. Undercover looks with bags of performance. Weight has a big big part to play in the performance of a car. I also have a 1996 Renault Clio Williams 2.0. No turbo. It pushes out a matching 150bhp but weights about 3-400Kg less than the Astra and performs accordingly so! I have ordered a new BMW 218i Gran Coupe to replace the Astra. I will miss her when she is gone…..
