At ASAP Motors, we have an innovative way to get you just the right engine. Take a few minutes to fill in the requested information, such as model year, transmission and drive train, etc. submit your online form, and typically within hours, or even minutes, you’ll start receiving offers via email. Peruse the engines listed, and feel free to contact the appropriate sellers with your follow-up questions. Inquire about the condition, warranty, engine history, and anything else that is important to you.
Remember that, as a prospective buyer, you are free to ask for better pricing or a longer warranty. Some sellers will have flexibility in their terms, and others will not. Of course, it never hurts to ask.
Explore Reputation
Once an engine of interest has been located, go online to check out reviews of the seller. Explore the supplier’s history with the Better Business Bureau if you wish.
Payment Methods
When it comes time to finalize the purchase, we highly recommend using a credit card or PayPal for your payment. Or, purchase a pre-paid Visa card. These methods all afford a buyer decent protection. By contrast, we suggest that one avoid checks, Western Union, or money orders. The goal is to have real peace-of-mind as the purchase is made.
Engine Shipping
Any supplier in our network will be more than happy to ship your 645i engine straight to the repair shop or dealership that will be doing the installation. ASAP Motors suggests that you go with ASE-Certified techs. You have a lot invested in your 6 series BMW, and having the utmost confidence in the work done is essential.
At ASAP Motors, we want to help you find the exact engine that you require. Our large network of suppliers stands ready to assist.
