One quick visit to Tim Leech later and sure enough I did. Tim, I can't thank you enough - we both love the car and that diesel means that I can afford to get to Brighton a lot more often than I used to.

I've put about 600 miles on it since I picked it up on the 23rd, what with all that Christmas visiting and so on, and it hasn't missed a beat. I felt like I was living in it as I didn't actually get home until yesterday! Now I won't be driving it again until the snow clears but that will be another long run.
It's a brilliant car - best BX I've ever been in. I hope I can carry on looking after it as well as the previous owners did.
Cheers again Tim, you've made a couple very happy! Kudos to my GF again too - I can't believe she's actively encouraging my car fetish!
The Saab will be on ebay as soon as I can take some non-snowed-in pictures of it.
