Welcome to the Tilleman Motor Co website and you will find that like our other customers 'YOU Win with Tilleman!'  You will find as you browse our inventory that we subscribe to Internet Value Pricing.  We present a low no hassle price to you based on polling over 20,000 pre-owned websites and comparing our equipment, miles and condition to other vehicles in real time.  We do not artificially inflate our pre-owned prices in the hopes of winning a negotiating contest with our customers. This gives you the assurance that everyone receives real time value pricing on every pre-owned vehicle we sell. Prices may be adjusted daily depending on this polling of other pre-owned vehicles. After business for 30+ years we realize that internet Value pricing is by far the best approach for our customers.

Enjoy our site and we hope to hear from you.
