Purchasing an insurance auction car

With the damage to the Santorin car being sufficient that my insurance company decided to total the car I was on the lookout for a replacement.  I was hoping to find a Santorin 6-speed so that following the transfer of components to the replacement car I would be back to where I was before the damage occurred.  It didn’t take too long to realize that finding a base S4 similar to mine would be exceptionally difficult.  I had specifically ordered my S4 without a sunroof and some other comfort options.  A Santorin 6-speed without a sunroof is probably a very rare car.

I opted to consider other colors with Silver being the first choice and other colors a possibility so long as the car could be purchased for a low enough price to make repainting the car a different color feasible.

I also left open the possibility of purchasing a Tiptronic (Automatic transmission) so long as the purchase price was low enough to allow me to fund a 6-speed swap into the car.

I was put in touch with an auto dealer who frequented auto insurance auctions and gave them the specifics of what I was looking for and what the maximum price was that I would pay for a car.  After a couple of weeks they sent me some information about a Silver S4 in Connecticut that was a theft recovery and would be going up for auction soon.

The fact that it only had 43,000 miles on it, was a single owner vehicle, and appeared to have minimal damage made it an appealing car.  I could live with the Silver color, but the tiptronic would need to go.  I wasn’t enthusiastic about bidding on a tiptronic so when it first went up for auction I passed on participating.

At the conclusion of the auction the highest bidder had offered $1600.  At that point I was kicking myself for not getting into the auction.  I’d been willing to spend up to $5,000 on one of these cars and whoever the high bidder was had just got themselves a great deal.

I went back to the auction site the following day to see if any new cars had come available and I saw that this Silver car was scheduled to go back up for auction.  A bit puzzled about this I contacted the auto dealer to inquire what was going on.  They informed me that the insurance companies have the option of accepting the high bid, or not and re-listing the car in the hopes of getting a higher price.  Now I was interested in this car since I’d figured about $2,000 would be needed to do the 6-speed swap, and if I could purchase this car for around $2,500 I’d be near my maximum for acquiring a replacement vehicle.

A week later the car went back up for auction and the dealer entered the auction on my behalf with a maximum offer of $2,500.  This time the bid price went up to $1700 and then stopped.  I was a wondering if I had been the high bidder when I received a phone call from the dealer telling me that I was the high bidder, but that the insurance company still had the right to refuse the offer and try to list the car again the following week.  I was told that they would hear from the insurance company some time during the day as to whether or not the offer was accepted.

About an hour later I heard from the dealer again letting me know that the insurance company had accepted my $1700 offer for the car.  Now I just needed to figure out how to get the car.

Composite pressure drop

The chart below shows an approximation for how the stock B5 S4 intake system compares against an aftermarket alternative.  The various system components were tested separately, so the composite results shown below do not accurately depict how all of the parts would measure if operating on the automobile.

Additionally, when on the vehicle the operating pressure would in many cases be much higher, which would cause the pressure losses to be greater.  Still, the chart gives some indication to the scale of improvement that can be obtained through the use of aftermarket or alternative parts, at the tested airflow of 500 CFM.

The legend shows the different configuration tested.  To the left of the slash ( / ) is the stock configuration and to the right is the modified and/or aftermarket configuration.

IC Info Summary

The following information is a summary of data I have personally recorded as well as information I have obtained by viewing the results provided by others.

This information should not be taken as ground truth, there can be variability in results dependent upon how a car is operated, what environment it is evaluated in, and how the information is collected.  The point of presenting this data is to make available to others the information that I use.

IC Summary DataIn the following scatterplot, products for which I do not have IAT data are shown along the vertical axis at an IAT Rise value of zero.
