Hi Andrew, hope you are enjoy Cougar life. I've had mine for over 5 years now and loved it. It's not had any problems that you wouldn't get with most cars. The only thing I did discover (too late) was that it is fussy about it's alternator. Worth a read up on the site before changing it if you ever need to.
