Unless someone has a genuine need, no car should be bigger than this.
@davidho I'd drive a Mini Cooper if it weren't for the Airstream I need to tow :-)

@devlord There is a very small Airstream, made of fibreglass instead of steel -- Bantam? Forget the name now. Possibly not made anymore. I know I considered it for use with a Wrangler. I've heard very different numbers for MINI's towing capacity, from zero to a tonne; I'd ask a dealer, directly. And if you do it, have the dealer put the tow package in, not some sketchy after-market job.

There used to be trailers made for Bugs, so I'm sure it's possible.

@devlord Bambi.

4.9-6.7 m long, 2.44 m wide, 2.88 m tall (w/ AC); single axle; GVWR = 1.588t

So, not for all vehicles, unfortunately. And not for MINI. The tongue weight alone is probably a deal-breaker.

But plenty of other trailers are light enough.

@wesdym they also have the Basecamp but I think it expects at least a small SUV.

@devlord I realized later I was thinking of Scamp, a different make.
