What soft roader could offer good ride comfort?
"I'm 81 and about to change from my BMW 3 Series convertible for something easier to enter and exit. It would be helpful to know if any "soft roader" matches the ride comfort of its maker's market niche-equivalent saloon. Overall ride comfort to include road noise, mechanical noise, seating, driving position and suspension compliance as determinants please. No longer bothered so much about performance and general handling sharpness."
The new Toyota C-HR is fabulous. Rides beautifully and handles brilliantly:

Are there any all-weather tyres available for my BMW convertible?
"I have a 2012 BMW 330d convertible. The wheels are 255/30/19 at rear and 225/35/19 at front. If I move to 17-inch wheels ( 225/45/17 tyres), are there any all-weather tyres available or would I need to buy winter and summer tyres separately?"
Michelin does Cross Climates in 225/45 R 17 94 W XL and in my experience over 10,000 miles these are the best all weather tyres. However, they are not runflats, and they are directional so tyre swaps to even out wear have to be front to back the same side. You can run the car on non runflats, but you would then either need to rely on the AA that carries universal space saver spare wheels to get you to a tyre depot, or carry a space saver spare. Tyre repair kit glop fails to repair around 95% of punctures.

Is there a method for testing xenon headlamp aim?
"I am ordering a new BMW M235i convertible. It is fitted as standard with xenon headlamps. As the car will be used extensively abroad, I need to ensure the headlamps will not dazzle other drivers when driving on the right at night. My local BMW dealer thinks the beam uses flat-beam technology to avoid dazzling when driving abroad so there should be no problem, but he has been unable to obtain final confirmation of this from BMW. How can I test the lights? "
Park the car facing a wall or a garage door about 50 feet away. Switch the headlights to full beam, then to dip. If the dipped beam drops down you're okay. If it shines to the left, you aren't.

Buying a used 3 Series - what should I watch out for?
"I'm in the process of trying to find a 3 Series BMW convertible. My budget will stretch to around 2007/2008 car from a trader. I want a petrol engine but would like to know any reliability issues or what to stay well clear from on the 325, 330 and 335?"
