The Avenir costs $13,500 more than the base model Enclave, and is the only trim level with the optional $2,095 technology package, which includes adaptive cruise control and a real-time dampening suspension. Buick says that 80% of Enclave Avenir models are sold with the technology package, which amounts to even more profit for the company. The sky is the limit for the Avenir sub-brand. Given that Buick has already affixed the name to the LaCrosse sedan as well, we could eventually see an Avenir version of every model in the lineup.
