Allan, you have owned a jalpa or two correct???
I will put some thought together when I have time, but all three of the drives I have owned have been ultra reliable; more so than some of my friends Hondas.
In eight years my current driver (411) as never needed the cam chains or timing adjusted. I have done oil changes and tune ups. I did have a throttle cable snap, but it was frayed when I bought the car ans still lasted 4 more years.
So in my opinion they are reliable as long as you make sure everything is running properly first. Case in Point. I was out two weeks ago in the 105 degree weather. Top up AC on high and it was 73 in the car and the car was running about 5 degrees warmer than normal. I have never had the car run hot ever. If your car runs hot something is wrong. It could be the thermostat, an air bubble (most common as the therm is the lowest point on the engine), bad fan switch, or clogged rad.
again cam chains not belts like a 308 so no built in maintenance.
Summit sell piston and rings (JE Piston set) they are exact size and are drop ins. Many parts are the same as the Countach, which also means a lot of fiat, VW, BMW, etc parts cross reference.
Tires in my opinion have been the hardest/most expensive part, but I have Bravo wheels so 15 inch rims are less and less common.
My engines do not burn oil, do not leak, etc.
Yes the cars are individuals and each one is a little different in how they like to act, but if you know what you are doing or ask the guys that do know you can do almost all the work yourself.
Tuning the car is "fun" and I am still working on doing it myself. FOr a 25 year old car all the gauges still work perfectly. The electronics are point to point so if something stops working it is easy to track down what is wrong and 9 time out of 10 it is a fuse that is corroded.
Yes I love my cars, but I have not had the issues that many people have had. The main reason IMO is I bought a good car, not a cheap car. Just like the guys who buy a CT for 70K and then end up putting 50-100K into it and hate it for how bad a car it is. If you buy a 20K Jalpa expect to put 20 plus into the car to get it running the way it should.
As for price I think the car is under appreciated and in time may command a higher price.... and owner can always hope.
Also many of the Jalpas have been owned by people who can barely afford them so they end up in disrepair because once the first bill comes due they stop fixing everything and sell it. Price again; I heard one guy had a choice between a Jamara and a Muira. He choice the Jamraa for about 3K less when brand new. The miura turned out to be the ultimate collector with Jamara values very low when compared. So one took off and the other did not.
I have not found it hard to find parts. Evans and Jacques have lots for sale and Evans Auto does tons of Jalpa restorations.
What are other peoples thoughts.
