Mercedes - $7150
Model: 190E 2.3-16 & 2.5-16 "Cosworth"

Back in the late 1970s, Mercedes competed in rallying with the big V8-powered Coupés of the R107 Series, mainly the light-weight Mercedes 450 SLC 5.0. Mercedes wished to take the 190 E rallying, and asked British race car engineering company Cosworth to develop an engine with 320 bhp (239 kW) for the rally car. This project was known as project "WAA" by Cosworth". During this time, the Audi Quattro with its all wheel drive and turbocharger was launched, making the 2.3-16v appear over-matched. With a continued desire to compete in high-profile motor sport with the 190, and also now an engine to do it with, Mercedes turned to the Deutsche Tourenwagen Meisterschaft (DTM) (German Touring Car Championship) motor sport series instead. Cars racing in this championship, however, had to be based on a roadgoing model. Mercedes therefore had to put into series production a 190 fitted with a detuned version of the Cosworth engine. This high performance model was known as the 190 E 2.3-16, and debuted at the Frankfurt Auto Show in September 1983, after its reputation had already been established. Three cars, only slightly cosmetically altered, had set three world records in August at the Nardo testing facility in Italy, recording a combined average speed of 154.06 mph (247.94 km/h) over the 50,000 km endurance test, and establishing twelve international endurance records.
Due to their performance, the 16 valve cars were different from the other 190 models. The body kit on the 2.3-16 and 2.5-16 reduced the drag coefficient to 0.32, one of the lowest CD values on a four door saloon of the time, whilst also reducing lift at speed. The steering ratio was quicker and the steering wheel smaller than that on other 190s, whilst the fuel tank was enlarged from 55 to 70 L. The Getrag 5-speed manual gearbox was unique to the 16 valve and featured a 'racing' gear pattern with 'dog-leg' first gear, left and down from neutral. This meant that the remaining 2nd, 3rd, 4th and 5th gears were in a simple H pattern allowing fast and easy selection. 
The strictly four-seater interior had Recaro sports seats with strong side bolsters for front and rear passengers. 3 extra dials - an oil temperature gauge, stopwatch and voltmeter - were included in the centre console. The 190 E 2.3-16 was available in only two colours, Blue-Black metallic (Pearl Black in the US), and Smoke Silver. The 2.5-16 added Almandine Red and Astral Silver.
All 2.3-16 valve 190 models are fitted with a Limited Slip Differential (LSD) as standard. 
The suspension on 16 valve models is very different from the standard 190 (W201). As well as being lower and stiffer, it has quicker dampers, larger anti-roll bars, harder bushings and hydraulic Self-Levelling Suspension (SLS) on the rear. This allows the rear ride height to remain constant even when the car is fully loaded.
At the inauguration of the new, shorter Nürburgring in 1984, a race with identical cars was held, with former and current F1 pilots at the wheel. A rather unknown young driver named Ayrton Senna took First Place in that race.

This car is a  1986 Bronze 190e-16v 133k miles excellent condition, all original other the suspension were upgraded using custom springs ( custom made to get the ride height and the rate I wanted) and Bilstein Sport shocks on four coners. All the SLS system is still  in the car just disable, if one wants to use the SLS, you can re-install it. 5 speeds,  AMG wheels. and camber links in the rear to allow you to adjust the camber setting. paint and body is in good condition, no dent.  Panasonic CD player in the trunk with CD changer draw, connected with the factory radio system. alarm system,  dash does have cracks and the rear seat center top needs to be re-shewn  2-3 inches long, the rest of the interior is in excellent condition. All gauges work other than the clock, sun roof, windows, seats all work perfectly.  It is a great car and handle absolutely great with the suspension upgrade. The car sits in garage when it is not used.
