SECOND-HAND SENSE: The numbers of convertibles evident in recent years suggests an almost indefatigable optimism completely out of kilter with our climate.
Dealers report a demand not driven by logic but by an enthusiasm to be different and to make the most of it when the sun shines. In recent weeks one could observe - between the clouds, the wind and the rain - car tops coming down in greater numbers than ever. And why not ?
Driving with the roof down certainly does make for more fun driving. Even the more sedate cars available in convertible form seem to adopt a certain style denied their saloon siblings. You will find you can enjoy sauntering around on a sunny day with a freedom not necessarily reflected in other parts of your mortgage-driven life.
There are quite a few convertibles on the second-hand market, but they tend to command a premium. One of the most impressive is the BMW 3-Series convertible, a car that has been around longer than many and which has not really changed greatly over the years, at least not in styling terms. It looks good with the roof up or down and, importantly for a convertible, it's well engineered and sturdy.
The qualities of the 3-Series have been well documented. Traditionally it has been better served by bigger engines and some versions can be a little rough in the ride department. However, it's a good package overall and there's no doubting its build quality.
The most popular convertible option is the 2.2 petrol, which has very good torque, or pulling power, and lacks nothing in ride and handling. It's also comfortable to drive with the roof down. Many convertibles have awful noise levels and control of wind funneling can be very uncomfortable. The 3 has a very good balance when it comes to both.
If you're in the market, look for one that has been well maintained and, if the roof doesn't come down and go up perfectly and smoothly, walk away. These mechanisms can be very tricky and very expensive to fix. Also remember coupés don't offer the level of comfort in the back, and boot space is limited.
There is no record of the convertible being subject to EuroNCAP crash tests, but the conventional 3-Series has scored a minimum of four out of five stars for driver and passenger safety.
Older models have had a number of recalls but BMW has been racing ahead in recent years in terms of quality. That's not to say things don't go wrong. In the past six years some 3-Series cars, but not all, have been recalled for problems with brake pedal servo links, unscheduled deployment of airbags, brake light failure and steering shaft corrosion.
The 2.2 doesn't come cheap. Nor is it cheap to run. A 2003 model with alloys, airbags, half-leather sports seats, air conditioning and various other extras and with 14,000 on the clock is on offer at €49,995. A 2001 car with many of the same features will cost about €38,000.
FOR: Classic enduring style and great fun to drive
AGAINST: Expensive to run and limited space in the rear and the boot
