Re: 156.. what value roughly
A car is worth only as much as the buyer is willing to spend.
Last November I was tempted to buy a 2003 reg'd 1.9JTD, list price was €27500, getting €6000 on a 98 Impreza with 100k+ miles on it.... so €21500 + car.
In Feburary, I almost, & sometimes regret not buying the same car, for €21500 straight.
Alfenia, i bought privately. She is a 2000 reg'd 2.0L T-Spark, with 62k miles, cost me €6400 [ + another €1200 since buying it...1/2 that was a timing belt ]. Same time as I was looming at Alfenia i was looking at garage prices too. Garage wanted between 2000 to 4000 extra for the same year & similar milage/spec.
