What should I rather take? Mercedes 300TE 4-Matic or Audi 90 quattro?

Hi you, I’m currently driving a 500 SEC (with the beautiful V8 and LPG – just great!) two weeks ago a girl drove up the back, and I get a bit of a kneading from the insurance company. Since the Daimler is not THE car for the winter anyway (I already noticed last winter – was already clear to me when I bought it), I am thinking about getting something else… I wanted to log off the star cruiser over the winter and watch it next year (the is ready to drive, and you can hardly see anything, but there are still little things to do here and there, etc. etc. etc.) and get me something else for the meantime. Since I have really good experiences with the Daimler, and I always wanted a station wagon, a 300 TE with 4-Matic has slipped on the list. Running power around the 320,000 km, with LPG (that would be my favorite). Equipment is rather not sooooo worth mentioning (compared to the 500s), but that’s not the case for me. Here I read in a little bit and found out that the 4-Matic (which is probably only in connection with the ASD) can be quite expensive if broken. The next possibility would be an Audi 90 20V coupé. My father also has such a… Audi is of course THE brand for all-wheel-drive vehicles, but here “disturbed” me the slightly higher price (approx. 1000 euros more expensive than the Daimler). For this lower mileage. Motor is considered a biblical cross-country runner. However, the whole thing unfortunately without LP G (which I really would like to have). Furthermore, the box in the insurance is more expensive than the Daimler… I have about 2200 euros available (although I would like to put something in reserve on the high edge, since I am currently Zivi). Or are there any other options? Had – because I used to be a Saab driver – already with nem 9-5 Aero or at least 2.3t, preferably then as a combi, eyed, but then I would have to give a) additionally to the Daimler in payment (which I hate to give in wil l) and b) the 9-5 from the engines is probably not as stable as the “real” Saabs (before GM times)… Thank you already in advance!
