"Right now,some people like me want to keep this daihatsu as the way it is."
Please explain - do you mean not restoring it?
Or do you mean keeping the original mechanical parts rather than putting in a later engine?
And yes, I do like spicy food. But more important I like rice and noodle meals (it's not what most people eat in UK)
By the way, do you know that particular Diahatsu in Chiang Mai? Is it still there? And was it originally a convertible or was the roof removed?
