Karibu sana mjuaji...
For anything to do with vehicles...I am your man.

Mostly I deal with Japanese. However,I would advise as below:

The price range will be:
Benz C180 - 500k-800k
CRV - 600K-800K

Of course the actual price will depend on the mechanical and body condition, mileage etc. Get a defect report before committing your money.
Please check out the car bazaar at Jamhuri Park on Saturdays for some leads.
Meanwhile, I will check around and update you in case of any new developments.

Drive your car to CMC and get a defect report,this wiill dff give you a rough ide aof how much you going to cough to them.

If you want to get the best bargain without compromising the quality, check on the chasis of your vehicle and record the colour code. You can take this to a paint manufacturer of your choice to have the color mixed. They use computer to ensure you get the same shade. You will however need to ascertain the amount of paint required. Once you have the paint. Take to a well known technician specialising in body work. I would recommend Auto Stylez in Buru. To have a glossy shinny service (just like new), they will only need to wax and buff the car after the second-layer painting. This will cost you about Ksh25,000 - Ksh 30,000 (all inclusive. You may need to add additional 5k or so in case they will paint inside the bonet (they have to put the engine down first). They did a wonderful job on my Pajero io for 30k.

@mjuaji try Unity Garage in Industrial area.i dont know the prices but you can talk to one of their sales people Mr.Edwin on 0722213702.
