Thanks for the suggestion. Even i thought about spending couple of thousand and fix everything once in for all. because i like its quirky old look and functionality. but again i changed my mind,
During my last drive my nativa abruptly blow some white smoke. next day i took it to mechanic he cannot find exact cause as there is no white smoke now. but when i opened radiator cap before i start the engine i saw little bit of oil in the coolant. not too much but little bit floating on top of coolant. but engine oil seams fine, mechanic’s guess is head gasket is failing again. but have to open up and see. also car overheat when its idling for at least 15 mins, So cooling system also needs to be fully checked
Apart from above another concern is lack of power. During last couple of drives I’m disappointed with performance, in quite steep incline the car wont climb as I wanted.
So decided to fix the car and sell it and go for long term reliable partner.
