OilBurner, you will find the best American Market value indicator on
www.ebay.com ....but I'm not saying you should buy your Benz there!!
$6000 is alot of payola for *any* 123 or 126 in this market where "disposable" products and spoon-fed desire for "newness" is the prevailing attitude which drives prices of smart purchase diesels with less than 200,000 miles through the floor.
Am wondering if with contacts in Germany you could purchase a very good 5-speed Autobahn edition 20 yr old 123/ 300Diesel (did they make them?) which is entirely unknown in this country...... AND ship it to Port Los Angeles..... All for less than $6000 USD.
But i know nothing about the German market. Otherwise, you might even find an exceptional 123/ 300CoupeDiesel in the USA for the money you are thinking of spending.
