I would recommend one, as a cheaper alternative to a CTR. Its not in the same league handling wise, its a bit soft. They really need a drop from standard (they sit like tractors lol!) which I've heard helps the soft handling a LOT. It is however, slightly more comfortable and a lot more affordable. Straight line speed are much the same, until you get over 90 ish when the CTRs displacement and torque pull it away.
Read this thread at your peril. I like to think I defended myself and my choice valiantly and factually, alas the CTS is not on OcUKs list of acceptable cars
