Any recommendations on places that do good economical service is appreciated!

I use a guy name Nai in Soi 45 on Sukhumvit Rd, close to Index Furniture shop. He is in Soi 45 inside about 300 Mater (not the one on the corner of Soi 45). I use him for all my rental and used cars for years. We all know, Noone is perfect, but the guy is honest and try to do the best and actually he have quite good common senses. Prices are not expensive. You can call him at 086 98588 01
