I had started on the same quest three weeks back with a similar budget. Thought I will sell my current ride and add in the deficit.
If you know of any honest dealer, please share contact details. There are many small showroom owners who are advertising here bat PW.
I ended up contacting 2 from PW and even though I absolutely love this site, I was least impressed with their 'integrity'.
They were selling JDM cars that had been driven locally without being registered, the odometer had been tampered with, or were adding 2-3 lacs on top of average prices. Some cars had shaky chassis even.
The only option I have is to go to the authorised dealer and opt for exchange, but I am being patient for 2 weeks and seeing if I can score a freshly imported JDM.
