Oscar, I am a Brit and I would never buy anything from MG Rover. That might give you some insight as to what I think of Rover group products.
The company I work for used to own Rover cars. As a consequence we get very good deals on Rovers and MGs (upto 33% discount, depending on what modesl they can't sell at the time) and thus a lot of people I work with have owned these cars in the past. Nobody has anything very positive to say about MG or Rover cars.
Build quality and reliability are not too bad, but we are talking similar to Chevy or Pontiac.
Do not confuse this MG car with the new MINI - different companies completely, in case you didnt know!
You would be much better with a Miata or an MR2 IMHO. Mazdaspeed Miata yum yum
You can pick up a Z3 (maybe a 3.0i, definately a 2.8 or 2.5) or a TT 180hp for the same money as you are looking at paying for the MG!!!
