那些实行一口价的合资品牌车型，现在都怎么样了？

Core Viewpoint - The implementation of fixed pricing policies by joint venture brands has had mixed results, with some models seeing increased sales while others remain stagnant, highlighting the complexities of consumer acceptance and market dynamics [5][8][10]. Group 1: Implementation of Fixed Pricing - SAIC Volkswagen is a pioneer in the fixed pricing policy, having started with the T-Roc model in August last year, with most models now following this approach [2]. - The execution of the fixed pricing policy varies based on how long a new car has been on the market, with stricter adherence observed in the initial months post-launch [3]. - Customers who are not in a hurry often wait for discounts, as dealerships may offer promotions within three months of a model's release [4]. Group 2: Customer Reactions - Customer responses to the fixed pricing policy are mixed; while some appreciate the straightforward pricing, the majority still desire negotiation and discounts [5][10]. - Sales personnel initially welcomed the fixed pricing model for reducing negotiation stress, but over time, they have recognized its limitations [9][18]. - Many customers, especially those who have previously purchased joint venture vehicles, are skeptical of a no-negotiation approach, feeling that it contradicts traditional buying practices [10][11]. Group 3: Market Dynamics and Competition - The effectiveness of the fixed pricing policy has diminished over time, with initial increases in customer traffic and sales not sustaining long-term [8][19]. - The slow pace of product updates among joint venture brands has led to customer dissatisfaction, especially when compared to domestic competitors who frequently upgrade their offerings [12][22]. - The fixed pricing model requires manufacturers to provide compelling products; without strong offerings, the policy may hinder competitiveness in the market [21][22]. Group 4: Regulatory Environment - Manufacturers have implemented strict controls over the fixed pricing policy, with penalties for dealerships that violate pricing guidelines [7][15]. - Despite initial strict enforcement, some dealerships have resorted to offering unofficial discounts to meet sales targets, indicating a potential breakdown in the policy's effectiveness [8][20].
