Hmm, if you find a good car then it is cheap, else a pain.
You need a good mechanic for the carburetor and engine tuning.
All parts are available kabli.
But if you want to enjoy a margalla, buy one with a good and healthy engine and rust free body.
Even then, expect to spend atleast 50k to make it something good.
Imo a margalla in 350k will be a money pit
