Got rid of one of my Jap cruisers today, Puts me back to only 5 cars. Actually 4 and a truck. Thinking about getting another NICE diesel, i.e. spend some actual borrowed money for a change. I was looking through autotrader at a bunch of SD's and SDL's, I'm thinking of going as new as '87 for the next car. Is there a dramatic difference between the SD and the SDL as far as power. Is there any great difference in reliability. I see the SDL is not a cast iron head which makes me a bit queasy. My last two cars were E-bay but this time I want to do a real eye-ball look and drive it before purchase. The SD, is that a 617 motor? Same as in my DT? I'm going to try to find a car that's "perfect", R-12 A/C, dry carpets, working defrosters etc etc, all the crap that makes me nuts on the D. Anyway, most here have more years experience than me so I'm asking basically should I go for an SD or an SDL or does it really matter. Thanks.
