BMW Z8.
What to Check Before Buying.

The BMW Z8 is a rare, hand-built roadster produced between 2000 and 2003, powered by a 4.9-litre V8 from the E39 M5. With fewer than 6,000 built worldwide and limited UK examples, it's a collector's piece rather than a daily driver. Values have climbed steadily, making a thorough pre-purchase check essential. Buyers should scrutinise maintenance history, watch for undisclosed accident damage, and verify authenticity of components given the car's desirability.

The average used car has 3+ known model faults the seller won't mention.
