The whole concept of a drop-top is that it should be stylish and desirable. Add to that the excitement of a high-revving engine and you have a car very few can resist.
Powered by a naturally aspirated 3.2-litre straight six, the E46 BMW M3 cabriolet delivers driving thrills by the bucketload and the best part about it is that examples can now be bought for less than £15,000. Need proof? Well, take a look at this unmolested 02-plate with its folding soft-top for £13,000. It has covered 38,000 miles since new, and you rest easy because the Bavarian comes with a full BMW service history, MoT and four new tyres.
Another German powerhouse is the previous-generation Audi S4 cabriolet, which has space for four adults and a big boot. If you can afford to juice the 4.2-litre V8 engine then look into it, because the rapid cabrio looks like a stellar secondhand buy; values are sitting close to £10,000. We tracked one down; it’s an 04-plate with 75,000 miles on the clock and comes with full leather, electric seats and climate control for a mere £12,500.
