I just want a rough idea of how much I should offer this for, i've only had the car 5months, but a friend is selling his sileighty, really cheap so I need the $$$

I paid $3200 for the car stock and unserviced.

The thing about cars is that extra's don't really add to the sale price. I'd definately take the head unit out, it might add only a few dollars to the sale cost. You'd be a couple of hundred up selling it individually! Or put it in your new car. You could even take out the speakers. If the person who is buying the car is into sound systems the head unit and speakers will be out anyway, and if they're not too bad :D. lol, if they are fussed you could put in a $30 one off Ebay and you'd still be ahead.

If the seat covers are good, take them out. They are only good for covering up dirty seats when selling! If the seats beneath are clean, wash them and use them on your new car. Another $100 saved on your new vehicle! If the seats are a little patchy you can put on a set of crappy seat covers for $20 and you'd still be up.

Headlight globes won't mean a thing. Even if they are the good high output ones. If you have high output ones (like 100W-160W H4's or 100W-150W H1's etc then I'd take those out and put them in your new vehicle, and replace them with the standard cheap globes which cost next to nothing.

You'd probably get around $3000 for it? I know that some people are getting them for as little as $2000 now after talking them down. A quick search on www.carsales.com.au etc. some people are wanting up to $6000+ for it, but you'd have to find someone really gullible to buy one at that price... The amount I suggested may be considerd by some as low, but if you set it like $3500 then you may not be able to sell it. People will talk you down so make some lee-way for that.

I think realisticly you're looking at around $1000-$1500.

I have purchased my last two 2nd gens for $1500 each, this one is a TS 1995 with 180,000km on the clock, with mags, and clean in and out, maybe i'm just lucky, i think around that price for yours would be highly acceptable amount to pay.

When ive had my injectors, timing and TB done im going to sell my maggot.
93 TR Sedan 2.6L Auto 160000km. Runs a lil sick right now for injectors but when its done will be fine.
Would clean up inside just fine if i could get the car in the driveway and vacuum it lol.
No dents etc, no noises from engine (ie chain etc). Gearbox is smooth.
Id be asking $2500 for mine, and id say yours with the extra km's would be about the same.

I know spending $500 on the car to fix all that stuff up and then selling it might seem stupid to some, but hey if i was looking at my magna to buy, id be saying $1000 with the way the engine runs lol.

It a big deal when it comes to the timing chain since I have started selling my car I have been asked when the timing chain had been replaced and by whom it was done.

This is all hard to say unless you could see the car with your own eyes to make a judgement.
