Not only expensive to buy in the first place, but very expensive to maintain!
Parts. And Service. Service, especially IF a person must rely on a dealership.
If a person has plenty of money or is perhaps a good mechanic themselves, maybe no problemo.
If I had one, it would have to be an older Turbo and the way that gas it today, where
do you get fuel with a high enough octane where their potential will be realized?
Racing gas, or Av gas at what? $10 a gallon?
Being as the CDI is so much less expensive, don't you truthfully prefer it?
Where do I start!
I'm not rich but at 65 I've collected a few older vintage sports cars over the years. My E320 is the most expensive car I've ever bought. I bought it new in 06 and have not had to put anything in it other than oil changes and tires. It has been very reliable for 122K. It gets 31-37 MPG and I'm very happy using it for my daily driver. My 87 930 has been very reliable and has cost me nothing so far. No racing fuel or AVGAS, just 93 octane at $3.45 or so per gallon (less than the diesel I put in the E320). Sure the 15-20 MPG is less efficient but it is not my daily driver. It's a fun car just like my 70 Stingray and my 56 Austin Healey 100.
You say you'd get an older Turbo. The 930 is the oldest Turbo (street) Porsche made. They were built from 1976-1989. Very few changes other than .3L added along with an intercooler a couple of years into production.
Parts, what parts. Porsche parts aren't any more expensive than Merc parts. Anyway, I'm pretty easy on equipment and haven't needed many parts. 930s are dead on reliable cars. I'm also a pretty fair shadetree mechanic although now if I do run into problems I've got good independents available on both my German cars and the Corvette and Healey are so straight forward I usually do the wrenching on them myself.
As to your last question - YES, I do (truthfully, as you say) prefer the CDI for its intended purpose, daily driver. I don't want to take anything away from it, I truly love my CDI. It's just a different experience than the Porsche. They both have their place. I put around 20K on the CDI and about 5K on the 930 per year.
To sum up - I try and understand the motives of others rather than questioning their motives. We are all different and should celebrate those differences. Your original reply to me seemed a little snarky, that's why I
asked what your problem with Porsches was.
Just wondering - Did you misread my first post and think I had a twin turbo? My comment about my twin turbo referred to the picture showing my CDI and 930 in the garage together. Hence, TT, get it? The CDI is a turbo, the 930 is a turbo, duh!
Please forgive me if I seem a little snarky with my comments, I'm really a very nice guy.
