Has anyone bought a new car within the last year or so in Kunming? If so could you tell us about the procedure, taxation, getting plates, hidden costs, good advice, anything really? Much obliged.

We got a new car last month.

First, I assume you have a Chinese driving licence. This is needed for insurance (talk about insurance below)

Procedure was simple.
Firstly you need to go to the police station and register your residence, and if your spouse is Chinese and does not have a Kunming HuKou she will need to register for a temporary residence permit at the same place (needed for vehicle licence, see below). Your spouse will definitely need photos for temp ID. I cannot remember if the expat does.
You will need to take original copies of your leasing agreement for the property you live at. There may even be a form the landlord has to fill in, I can't remember but the cop shop will advise.
Need photocopies of your passport main page and visa.
Total cost so far, about 200rmb.

Now you can buy a car (at any time you can choose a car and if it is not in stock they will order but will require a deposit, not sure how much). I think it is 30% deposit/down-payment required. If needed find a bank to loan you the money. Usually over 3 years, you can get 5 years. GM finance also do loans but are more expensive, and only for GM cars.
Some banks want you to take out loan insurance, not sure how much, but not a lot, and will vary with size of loan.

Pay for car in full, then you can register it. The dealer will usually help with all the process.The dealer, with the vehicle documentation will accompany you to get all the official stuff done.

Insurance agent. There is one in the same area as the Kunming vehicle registration office (call it DMV for ease). Insurance varies on the car. In China it is the car that is insured for any driver, not the driver that is insured. There are different levels of insurance.

Legal minimum is, I think, under 100rmb. This only compensates anyone you kill or injure, basically. Not recommended.
We got fully comprehensive equivalent. If we bend the car, the insurance covers it.

You will be given a certificate and a window sticker (sticker is legal requirement, don't loose it)
Cost of insurance 10.5k for car of value 300k, 3.2 L engine.

Vehicle tax and registration is done at the DMV.
Tax on our car was about 3k, not sure exactly.
We produced our insurance, and registered the car. There is a random numberplate selector on a computer and you have 5 lucky dips and then pick your favourite. You can then get your plates in about half an hour. Or you can try to select a plate of your own, and in a week they will tell you if it is available.

Plates are then given to you and you are given a little Vehicle License Book, you go to another window and you pay a fee, present insurance and they stamp your vehicle license.
Costs, I think under 300 rmb.

The car is now yours.

The dealer can now decorate your car, fit your GPS, tint the windows etc.
Costs unlimited ;-)

I would recommend tinting the windows, and there is a special film for the windscreen that deflects heat. This stops the dashboard from cooking, recommended but will cost more than the rest of the car windows to do.

TOTAL ON THE ROAD COSTS
Depending on the value of the car (small cars are cheaper) the on the road additional costs are about 45k rmb. With tax and insurance. For a car of cost 300k.
I think we were quoted approx on the road costs of 35k for a car of 200k value.

A bit vague on this, sorry.
Your dealer can advise better.

Thanks. You mentioned the tax being 3K for a 300K car. Did you mean 30k? I think I heard it's supposed to be 10 percent of the buying price.

Grats on your new wheels. I'll keep you in mind next time I get into a taxi from the Kunming DeathTrap Company :)

Yep, I meant 30k
