Hello, I got Camry 1999, 221km, and this is my 1st car. It runs, but there are some problems appearing (like rear light failure warning, or driver door electric lock doesn't work). So, I would like to know what tools would you suggest to have just in case? I checked battery, it is fine.
1. Multimeter, what type and where you suggest to buy
2. Test light,.....
3. What else?

If you're checking into electrical faults then a multimeter from Harbor Freight Tools ($5 on sale) or a Craftsman on sale at Sears ($11) should work fine. You probably dont' need a test light now if you have a multimeter, and some test lights shouldn't be used on electronic ignition systems because of current draw anyway (can damage transistors):

Craftsman Multimeter, Digital, with 8 Functions and 20 Ranges
$11 on sale Sears Item# 03482141000 | Model# 82141

Or HFT $5 on sale:

If you are going to be doing your own oil changes and transmission fluid drains/refills, then a metric socket set and hex bit sockets (for transmission and differential drain bolts) at HFT, 6 Piece 3/8" Drive Metric Hex Bit Socket Set. Or just get a single 10mm one $5.49 at Sears (Sears Item# 00942679000 , I think the $8.99 HFT set is a better deal myself, but you likely won't need the others):

plus an oil filter wrench especially good for the smaller I4 filter:

A mechanic's tool set like:
HFT $32, but you'll need an additional 1/2" metric socket set for heavier work and maybe a few others later:

http://www.harborfreight.com/10-piece-high-visibility-12-drive-metric-socket-set-67916.html

Or the Sears 118 pc set on sale $54-60 has most sockets you'll need, but has only 1/4" and 3/8" ratchets, not the 1/2"-drive ratchet. IMO this is the better deal and you can get a HFT 1/2" ratchet later if needed:
http://www.sears.com/shc/s/p_10153_12605_00934118000P?prdNo=24
1/2" HFT ratchet, $12 on sale:

1/2" set of extension bars:

Or build them separately starting out with a 3/8" set and then a 1/2" set with a short extension bar and a 14" breaker bar, but these are only metric:

http://www.harborfreight.com/16-piece-high-visibility-12-drive-metric-socket-set-67988.html

For tire rotation a 18" long (or 25" long for more leverage but clumsy) 1/2"-drive breaker bar:

http://www.harborfreight.com/12-drive-25-breaker-bar-67933.html

I would also pick up a set of torque wrenches when the sale prices are like $12-19 each or so.

Plus other basic hand tools like screwdrivers, pliers, etc.
