Welcome to the forum Denrak. If you want the peace of mind of knowing you just got the best price possible, do the following:
- get the dealers cost price from
Car Cost Canada - Home Page for the car and extras you want. You pay for this service - but you will save thousands of $.

- note the MSRP mark up is usually about 10% on the car and 15% on the extras.
- Go to the dealer with a print out of the carcostcanada numbers and your written offer, including your telephone number. Tell the dealer you are ready to buy a car today. Note that dealers have to meet monthly, quarterly and annual sales quotas - so end of the month or end of quarter are the best times to get a good price. Offer $ 1000 above dealer cost ( profit ) for the car and extras. If the dealer stalls - just walk out and advise they have 24 hours to telephone you, to accept the offer.

- if you have a trade-in, establish the wholesale price beforehand, from the library, bank or kelly blue book - so you know exactly how much / little the trade is worth in the deal.
If the first dealer does not accept your offer, then fax it to all other dealers in your area.
I have used this method to buy several cars - it works.
Enjoy your new car.

PS. Do NOT pay any 'documentation fee'. This is straight profit and is a deal breaker.
PPS. You can buy a low mileage demonstrator, in new condition, for about $ 5000 under new price!
