If you are tired of expensive car problems, buy one of these, it is cheap and good


Small things... like bulbs, brake pads, broken manual window lever, Clutch failure (all very inexpensive repairs).

Seats had to be rebuilt because this was used as a taxi...

Starter had to be rebuilt-75 euros at a Bosch authorized dealer.

General Comments:

Extremely reliable and inexpensive to repair. This 240 diesel engine seems to be indestructible.

Very good suspension and very good braking system (front and rear ATE system).

There is no smoke in annual inspections, and the engine can run on diesel fuel with vegetable oil added at a ratio of 20%.

This is not a fast car, but it is reliable, incredibly reliable...

Would you buy another car from this manufacturer? Yes

You can run more veg oil than 20%! I ran one on veg oil for years. Just added 5% petrol as anti coagulant.

How long did you run it at the petrol/WVO ratio?

I'm thinking of buying an old Merc diesel that runs on vegetable oil. Does yours start fine when it's cold? Any problems, tips, solutions?

It's a wonderful car!


The starter clutch stopped working.

The starter run, but it did not engage.

General Comments:

This is a wonderful car. I drive it every day. Although the starter was not working good since the moment I bought the car it took 2 years to finally stop working.

It's a pity that it is rusted beyond repairs...

When the time comes that I cannot drive it I will buy another like it!
