The median 2006 SLK-Class in the Canadian market sits at $24,900. That's your anchor. If you're looking at one priced well above it, you want a clear reason, and if it's well below, you want to know why.
Most of these cars land between $20,075 and $28,971. That's roughly a $9,000 spread, which is wide for a single model year. A near-$29k ask isn't automatically a rip-off, and a $20k car isn't automatically a project. Condition and history are doing the work inside that band.
What the numbers tell a buyer
Half of the 2006 SLKs out there have crossed 96,000 km. So a car with mileage in that neighbourhood is normal, not high, and shouldn't carry a penalty on odometer alone. Under that figure, you're on the fresher side of the pack. Well over it, factor in the wear.
We've flagged 3 deals on this model year in the last 90 days. These are cars priced below where the market says they should be. Three isn't a flood, so if one surfaces at the low end of that range in good shape, it's worth a serious look before it moves.
The short version: use $24,900 as your reference, expect to negotiate somewhere inside the $20k to $29k band, and don't overpay for a car just because it reads under 96,000 km. That mileage is the middle of the road here.
