Thanks fellers for all your advice and comments. I did purchase the vehicle after giving it a good check over and test drove it for approx 50 miles :). This is what I found: Bodywork excellent, all panels straight and only minor age related marks such as minor scuffs on bumpers and slight stone chips on front valance, amazingly the bonnet is fine. All keyfob controls work fine. M3 wheels with recently fitted tyres. Charcoal velour interior with no rips, holes or damage to seats, genuine BMW mats, load cover and dog guard, spare wheel, jack, tool kit and triangle, 6 CD changer all present in boot. Interior does need a good clean though (will be busy today). Under bonnet, all fluid levels checked and found to be adequate and clean, no evidence of oil or water leaks, no evidence of botched repair jobs etc. Started from cold fine and temp gauge moved up to the 12 o'clock mark gradually and stayed there for the complete drive (approx 40 mins). Smooth power delivery in all gears, changed through gears with ease, no unusual noises from engine, transmission, steering or suspension. Drove through minor B roads, A roads and M-way, pulled like a train when accelerating onto M-way (checked in mirror, no black smoke). All switches, controls etc working as they should be. Brake pad warning light on dash, owner ensured me that the pads are fine probably a loose wear indecator wire (will need to check this out) Front nearside headlamp bulb out (also indicated on dash). Full BMW service history up to 2009, private thereafter with reciepts. MOT Feb 20012. HPI report. I even had the cheek to barter the price and came away with the car for £1850 !!!
