I think 14% is high for a fixed rate and don't feel the Etios is worth that price.
You can get a lot more car for your money when you go 2nd hand.
How does one ensure a 2nd hand car is not a dud, besides doing a thorough inspection/AA checks and service history check?
As long as a car didn't start its life as a dud, has not been modified or abused like ****, is prang free and has been serviced regularly, it should be fine.
There are a couple of things you can do to
try protect yourself but some depend on if you buy from a stealership, 2nd hand dealer or privately.
Always do a multi-point check/road worthy check, see if you cant get the seller to pay(private finance clients often get a discount).
If you hang around there for the check, you can ask the inspector if he spotted anything odd, damaged, resprayed or repaired.
Always do a TransUnion check (not the value one) on the car, its not expensive compared to the car.(done as a last check before buying) This "should" have all the car details(vin, engine, reg numbers ect... MAKE SURE THEY MATCH THE CAR AND CARS PAPER WORK), Claim history, stolen recovery check(maybe check with cop shop anyway), etc. (Some times cars could have been repaired and no info is shown in the report)
If buying from a 2nd hand dealer/stealership, see if you can get the details of the previous owner (check the owners manual or service receipts for names, surnames and sometimes phone numbers). Call them, ask about the history, mileage when they sold it, how long ago they sold it, services and why they sold it, they have nothing to lose.
Check the service history, where it was serviced, call them and verify what was done, when it was done, if they noted any damage at the time, also verify the mileage on the clock, the mileage the service center has and the mileage in the service book are aligned.
(this shows if the odometer has been tinkered or/and if the dealer made up a service history)
See if the remainder of the warranty/service plan is transferable (often easier if you buy from a stealership). Ensure you transfer it as soon as you have bought the car. (if these have expired, you can get a 3rd party service agreement/insurance/extender/warranty)
Test drive it in as many conditions/environments you can. Driving a car in the rain can reveal a lot that you might have missed on a dry day, think electrical faults, leaks and more. Bring someone along, jump in the back and let them drive and see what you notice.
Test and inspect everything (don't forget mats, carpet, rear wiper, sprayer, cigarette lighter, boot light, the spare tire and her mother).
If you can, pull back carpets or boot liner and look for repairs, over spray or anything odd. Generally repair clean up is sub-par in areas you cant easily see or normally don't look at.
Sometimes things like missing service books, owners manuals, radio user guides, not original windows/windscreens, mismatched tires can be treated as warning flags and should be questioned.
Also look out for things that should be worn to a degree but seem brand new (pedals, gear knob, stuff)
Google things to lookout for when test driving and inspecting a car.
Once you have test driven a car, don't let the sales person pressure you into anything, find the hidden costs and stick to your budget, you owe the sales person nothing, this is their job they are not doing you a favor.(Don't be a d!*k)
Remember you don't have to buy that car.... there are others
If you have the opportunity take it to a body shop and ask if they spot any damage. (You might be able to do this on a test drive other wise do it just after buying it)
If any obvious problems or work is needed, get the seller to fix it before you buy. Remember to ask for receipts/proof of the repairs and re-inspect the car.
As soon as you own the car, take it for a service (this may be compulsory with 3rd party warranties anyway). Get them them to check everything.
If you couldn't earlier get a body shop to look at it for any hidden damage or history. Get the wheels balanced and aligned.
If undisclosed/deliberately hidden damage is found or repairs are needed, contact your bank/financier let them know, they will advise you. You may have to return the car. Keep all the bills/quotes/invoices (Id recommend making copies of them.... just in case you are dealing with a real shyster). If they do all the repairs, request all the receipts/proof and then re-inspect everything.
Remember the CPA is your friend when dealing with stealerships and 2nd hand dealers. Your bank/financier is there to look after your/their investment. Read and understand all the paper work. Make sure everything matches the physical car, paperwork, documents, everything.
